The Greenstar Highflow 440 is a floor standing, energy saving boiler, suitable for a large family home such as a 2 bath house with a regular requirement for 1 or more simultaneous draw offs of hot water. It has a built in condensate pump which increases boiler siting options. As a result it can be sited directly underneath a worktop as all servicing can be undertaken from the front of the boiler.

The boiler can be used to provide domestic hot water only when first installed with radiators added at a later date as you move to a full central heating system.

Worcester Bosch claim that 97% of the gas consumed by the Greenstar Highflow 440 combi boiler is converted into heat for the heating and hot water system. This is achieved by recycling exhaust gases to extract and reuse the latent heat they contain. As the gases pass through a heat exchanger they are cooled to 55 degrees as the latent heat is released and transfered back into the system. This approach also reduces carbon dioxide emissions into the atmosphere.
